1. Kev txhim kho kev nyab xeeb kev ua haujlwm
PO daim ntawv cog lus nyob rau hauv lithium hlau phosphate siv lead ua yog ruaj khov thiab nyuaj rau decompose.Txawm tias nyob rau hauv qhov kub thiab txias, nws yuav tsis tawg thiab ua kom sov los yog tsim muaj zog oxidizing tshuaj nyob rau hauv tib lub qauv lithium cobalt oxide, yog li nws muaj kev ruaj ntseg zoo.Ib daim ntawv tshaj tawm tau taw qhia tias hauv kev ua haujlwm tiag tiag, ib feem me me ntawm cov qauv tau pom tias hlawv hauv acupuncture lossis kev sim luv luv, tab sis tsis muaj qhov tawg.Nyob rau hauv qhov kev sim overcharge, high voltage them uas yog ob peb zaug siab dua tus kheej-tso tawm voltage tau siv, thiab nws tau pom tias tseem muaj qhov tshwm sim tawg.Txawm li cas los xij, nws txoj kev ruaj ntseg overcharge tau txhim kho zoo dua piv rau cov roj ntsha electrolyte lithium cobalt oxide zoo tib yam.
2. Txhim kho lub neej ncua
Lithium hlau phosphate roj teebhais txog lithium ion roj teeb siv lithium hlau phosphate ua cov khoom siv electrode zoo.
Lub voj voog lub neej ntawm lub neej ntev ntawm cov roj ntsha lead-acid yog li 300 zaug, thiab qhov siab tshaj plaws yog 500 zaug.Lub lithium hlau phosphate fais fab lithium roj teeb muaj lub neej voj voog ntau tshaj 2000 zaug, thiab tus qauv nqi (5 teev tus nqi) siv tau mus txog 2000 zaug.Lead-acid roj teeb uas zoo ib yam yog tshiab rau ib nrab xyoo, laus rau ib nrab xyoo, thiab kev tu thiab tu rau ib nrab xyoo, feem ntau 1 mus rau 1.5 xyoo, thaum lithium hlau phosphate roj teeb siv nyob rau hauv tib yam kev mob yuav muaj. lub neej theoretical ntawm 7 mus rau 8 xyoo.Xav txog kev nkag siab, qhov kev ua tau zoo-tus nqi piv yog theoretically ntau dua 4 npaug ntawm cov roj ntsha lead-acid.Kev tawm tam sim no tuaj yeem them sai sai thiab tso tawm siab tam sim no 2C.Nrog rau lub charger tshwj xeeb, lub roj teeb tuaj yeem them tag nrho hauv 40 feeb ntawm 1.5C them.Qhov pib tam sim no tuaj yeem ncav cuag 2C, tab sis cov roj ntsha lead-acid tsis muaj qhov ua tau zoo.
3. Kev kub siab ua haujlwm zoo
Lub ncov tus nqi ntawm lithium hlau phosphate hluav taws xob cua sov tuaj yeem ncav cuag 350 ℃ -500 ℃, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ib ncig ntawm 200 ℃.Kev khiav hauj lwm kub ntau (-20C-75C), nrog rau kub tsis kam, lithium hlau phosphate hluav taws xob cua sov ncov tuaj yeem ncav cuag 350 ℃ -500 ℃, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ib ncig ntawm 200 ℃.
4. Muaj peev xwm loj
∩Thaum lub roj teeb rechargeable yeej ib txwm them tag nrho thiab tsis tawm, lub peev xwm yuav sai sai poob qis dua tus nqi peev xwm.Qhov tshwm sim no hu ua lub cim xeeb nyhuv.Zoo li nickel-hlau hydride thiab nickel-cadmium roj teeb, muaj kev nco, tab sis lithium hlau phosphate roj teeb tsis muaj qhov tshwm sim no.Txawm hais tias lub roj teeb nyob hauv lub xeev dab tsi, nws tuaj yeem them thiab siv sai li sai tau thaum nws them.
6, lub teeb nyhav
Lub ntim ntawm lithium hlau phosphate roj teeb ntawm tib lub specification thiab muaj peev xwm yog 2/3 ntawm lub ntim ntawm cov lead-acid roj teeb, thiab qhov hnyav yog 1/3 ntawm lead-acid roj teeb.
7. Kev tiv thaiv ib puag ncig
Cov roj teeb lithium hlau phosphate feem ntau suav hais tias tsis muaj cov hlau hnyav thiab cov hlau tsis tshua muaj (lub roj teeb nickel-hydrogen yuav tsum muaj cov hlau tsis tshua muaj), tsis muaj tshuaj lom (SGS ntawv pov thawj), tsis muaj kuab paug, raws li European RoHS cov cai, thiab qhov tseeb. ntsuab roj teeb daim ntawv pov thawj.Yog li, vim li cas vim li cas cov roj teeb lithium-ion tau nyiam los ntawm kev lag luam yog qhov tseem ceeb vim kev xav txog kev tiv thaiv ib puag ncig.Yog li ntawd, lub roj teeb tau suav nrog hauv 863 National High-tech Development Plan thaum lub Kaum Ib Hlis Tsib Hlis thiab tau dhau los ua qhov tseem ceeb hauv kev txhawb nqa thiab txhawb nqa lub tebchaws.Nrog rau kuv lub teb chaws nkag mus rau WTO, kuv lub teb chaws kev xa tawm ntawm cov tsheb kauj vab hluav taws xob yuav nce sai, thiab cov tsheb kauj vab hluav taws xob nkag mus rau Tebchaws Europe thiab Tebchaws Meskas yuav tsum tau nruab nrog cov roj teeb tsis muaj kuab lom.
Txawm li cas los xij, qee tus kws tshaj lij tau hais tias kev ua qias tuaj ib puag ncig los ntawm cov roj ntsha lead-acid feem ntau tshwm sim hauv lub tuam txhab cov txheej txheem tsim khoom tsis tu ncua thiab cov txheej txheem rov ua dua tshiab.Ib yam li ntawd, cov roj teeb lithium-ion muaj nyob rau hauv kev lag luam hluav taws xob tshiab, tab sis lawv tsis tuaj yeem tiv thaiv cov hlau hnyav.Lead, arsenic, cadmium, mercury, chromium, thiab lwm yam hauv kev ua cov khoom siv hlau yuav raug tso rau hauv plua plav thiab dej.Lub roj teeb nws tus kheej yog ib hom tshuaj lom neeg, yog li yuav muaj ob hom kev ua qias tuaj: ib qho yog cov pa phem ntawm cov txheej txheem excrement hauv kev tsim engineering;lwm qhov yog cov pa phem ntawm lub roj teeb tom qab nws tau muab pov tseg.
Cov roj teeb lithium hlau phosphate kuj muaj lawv qhov tsis txaus: piv txwv li, kev ua haujlwm kub tsis zoo, tsis tshua muaj kais ntawm cov khoom siv cathode, thiab lub ntim ntawm lithium hlau phosphate roj teeb uas muaj peev xwm sib npaug yog loj dua lithium-ion roj teeb xws li lithium cobalt oxide, yog li lawv tsis muaj qhov zoo hauv cov roj teeb me me.Thaum siv cov roj teeb lithium fais fab, cov roj teeb lithium hlau phosphate zoo ib yam li lwm cov roj teeb, thiab lawv yuav tsum tau ntsib teeb meem roj teeb.
